Following the South African Reserve Bank’s (SARB) recent decision to reduce the repo rate by 25 basis points to 7%, South African consumers are increasingly asking how such changes affect vehicle finance. WesBank, one of the country’s leading vehicle and asset finance providers, is stepping in to clarify the practical implications for both new and existing car loans.
At its core, the repo rate is the interest rate at which the SARB lends money to commercial banks. Changes to this rate ripple through the economy, directly influencing the prime lending rate—the interest rate banks offer consumers. When the repo rate rises, borrowing costs for banks increase, often leading to higher loan interest rates for customers. Conversely, a lower repo rate makes borrowing cheaper, potentially resulting in lower monthly repayments for consumers.
“The repo rate plays a crucial role in vehicle finance affordability,” says Lebo Gaoaketse, Head of Marketing and Communication at WesBank. “Understanding how it works empowers consumers to make informed decisions when purchasing a new vehicle or managing an existing loan.”
Fixed vs Linked Interest Rate Vehicle Finance
WesBank highlights two main interest rate structures in vehicle finance:
Fixed interest rate finance: A fixed-rate agreement ensures that the interest rate—and therefore the monthly repayment—remains constant throughout the loan term. This stability provides peace of mind, shielding borrowers from fluctuations in the repo rate. Fixed rates are often slightly higher initially but are particularly advantageous in a low interest rate environment, offering protection if rates rise in the future.
Linked interest rate finance: Linked loans, in contrast, tie the interest rate to the prime lending rate. Monthly repayments can decrease when interest rates fall, but they rise when rates increase. This structure allows borrowers to benefit from declining rates, but requires careful budgeting, as repayments fluctuate with economic conditions.
“Choosing between fixed and linked rates depends on your financial situation and appetite for risk,” adds Gaoaketse. “Each option has its advantages, and our consultants are available to help customers select the best fit for their needs.”

Real-World Example
To illustrate, consider a linked interest rate vehicle loan of R300,000 over 72 months with no deposit or balloon payment:
- At the current prime lending rate of 10.5%, monthly repayments are approximately R5,725.
- Earlier this year, when the prime rate was 0.5% higher, the same loan would have required monthly repayments of R5,802.
While the difference—just R77 per month—may seem minor, over the full term of the loan, borrowers could save as much as R5,532. For fixed-rate agreements, monthly repayments remain unchanged regardless of interest rate fluctuations.
Managing Vehicle Finance in a Changing Interest Rate Environment
WesBank encourages consumers to take proactive steps to manage their car loans:
- Review your loan agreement to understand whether your interest rate is fixed or linked.
- Budget for fluctuations if your loan is linked to the prime rate; your monthly instalments could rise or fall.
- Explore refinancing options in a lower interest rate environment to potentially save money over the loan term.
- Consult a WesBank specialist for personalised guidance on managing repayments during economic shifts.
“Interest rates are a key factor in South Africa’s economic landscape, affecting all indebted consumers,” concludes Gaoaketse. “Whether you’re on a fixed or linked finance agreement, the repo rate directly impacts your loan. At WesBank, we are committed to helping our customers navigate these changes with confidence and make decisions that align with their financial goals.”
